As optimal technical scheme, this shield shell has at least one ground strip, be welded on the wiring board of external device (ED), go out in order to the electromagnetic wave drainage by absorption.
As optimal technical scheme, at the free end of this guide-joining plate, also there is a reverse bend, and namely this contact site is located at the bottom of the arc of this bend; So, guide-joining plate can be protected abnormal distortion can not to occur in the moment with ground terminal contact or lose.
As optimal technical scheme, connector in an assembling process, is be serially connected on same material strip by multiple signal terminal and earth terminal in advance, is imported once in the slot of insulating body, removed by material strip behind complete location by tool; Whereby, can keeping the external connection end of the plurality of signal terminal and earth terminal in same level, making to reduce the generation of slipping up when being connected by SMT with the wiring board of external device (ED), and be more conducive to assembling.
The utility model can reach following beneficial effect:
One, by the contact of guide-joining plate and earth terminal, this guide-joining plate is connected to shield shell again, the scope of integral ground between connector and this external device (ED) is increased, more promotes the reliability of ground connection and remove the ability of noise interference, to meet the transmission demand of this high-effect signal of LVDS.
Two, on this guide-joining plate one end system fixed mask housing, the axial other end is a free end and bends towards earth terminal, make that it can produce elastic reaction relative to shield shell and just like an elastic arm, the contact relation that the contact site of guide-joining plate is pressed against on ground strip is more certain.
